Titanium performance and major application fields

Titanium performance and major application fields

   Titanium is very similar to the appearance of the steel, a density of 4.51 g / cm 3, the lack of 60% of steel, a refractory metal in the lowest density metal element.
   First beneficiation technology needed to enhance and improve the quality of titanium in titanium concentrate; the second is to achieve recovery of titanium and vanadium, while direct reduction of new processes need to be further improved, after the successful application of titanium tubes and vanadium utilization will increase substantially and create for rare metals recycling chromium, nickel, copper, gallium and other conditions; third is to enhance the utilization of blast furnace slag, put a lot of our Sefstromite as iron, steel with titanium recovery of less than 25%, resulting in a lot of waste of resources, it is necessary to break through the high titanium slag recycling technology; Fourth, the development of high-end applications titanium, vanadium alloys, open the breadth and depth of the market, increase the demand as soon as possible.
   Titanium in the air at normal temperature is very stable. When heated to 400 ~ 550 ℃, the solid outer layer of an oxide film is generated, since the effect to avoid further oxidation of maintenance. Titanium absorbs oxygen, nitrogen, hydrogen can be very strong, such a gas is a very harmful impurity metal titanium, even if little content (0.01% to 0.005%) can seriously affect its mechanical function.
   Mechanical properties of titanium that is known as the mechanical function is associated with a very pure. High titanium machining function with excellent elongation, shortening section rate is good, but low intensity, discomfort collaborative planning information. Commercially pure titanium rods containing an excessive amount of impurities, has high strength and plasticity, suitable for production planning information.
   In the compounds of titanium to titanium dioxide (TiO2) is most practical value. Ti02 on the human body was lazy, non-toxic, it has a series of excellent optical properties. Ti02 opacity, gloss and whiteness, refractive index and scattering force, hiding power, good dispersion, pigment made of white powder, commonly known as titanium dioxide, the use of a wide range.

Titanium and titanium tube and vision in the use of desalination industry analysis

Titanium and titanium tube stock and vision in the use of desalination industry analysis

   Water is the source of life, fresh water is an important resource for human survival and development. About 70% of the area of the earth is covered with water, 97.5% of the water is sea water, the remaining 2.5% of the fresh water, fresh water available only 0.26% of the total amount of water in the earth. Currently, the global water shortage is worsening, our country is a serious shortage of water resources in the country, the water shortage is one of the major issues constraining the sustainable development of our society and economy. Desalination is currently opening up new sources to achieve the sustainable use of water resources, water scarcity and effective method of human settlement.
According to the "Twelfth Five-Year" period desalination industry development goals by 2015, China's desalination capacity will increase 3 to 4 times.            Desalination capacity doubling means double the investment, that in the coming years the country will increase investment in the desalination industry, and therefore, our desalination industry will usher in a period of rapid development.
Titanium and titanium tube as an important raw material desalination industry applications, with the rapid development of the desalination industry, China's titanium industry will usher in new opportunities and development opportunities. For desalination technology and applications of titanium and its alloys in seawater desalination industry overview, and titanium and its alloys in the foreground application desalination industry is analyzed.
   Of course, the desalination industry as new applications of titanium market, opportunities and challenges. We believe that under the strong support of national policy,titanium tube and its alloys will be widely used in water desalination project, which is to open up new applications of titanium market will play a great role.
   We know that, as the "Ocean metal" titanium and its alloys have excellent corrosion resistance in seawater, natural water is all most corrosion-resistant metal material, the corrosion resistance of stainless steel in seawater is 100 times and low density, high strength, good heat resistance. Therefore, material properties, reliability, service life, maintenance and other aspects into account, titanium and its alloys is undoubtedly the most competitive desalination plant material. Titanium used in desalination device comprises a heat exchanger, brine heaters, condensers, distillation, evaporators, pumps, valves, pipes, etc.

Industry titanium plate series of knowledge sharing

Industry titanium plate series of knowledge sharing

    Tube made of titanium plates, also known as titanium tubes, titanium or titanium plate suppliers with titanium tubes with welded after forming a curl. Titanium plate production process is simple, high production efficiency, different specifications, less investment in equipment, but the general strength of less than seamless titanium tube. 20 since the 1930s, with the progress of high-quality titanium tandem with the rapid development and production of welding and inspection techniques, and continuously improve weld quality, varieties and specifications titanium plate increasing and more and more fields instead seamless titanium tube. Titanium plate in the form of divided straight seam weld titanium tube and spiral titanium tube. Titanium straight seam pipe production process is simple, high efficiency, low cost, rapid development. Strength titanium spiral pipe is generally higher than titanium tube straight seam high, can narrow the billet production of large diameter titanium tube, you can also use the same width of the billet production of different diameters of titanium tubes. However, compared with the same length of straight pipe seam weld length of 30 to 100%, and lower production rate. Therefore, most of the smaller diameter titanium tube straight seam welded, large diameter titanium tubes are mostly spiral welded.
   1. Low transmission fluid with titanium plates (gb / t3092-1993), also known as general titanium tubes, commonly known as the clarinet. Titanium plate is used for conveying water, gas, air, oil and heating steam and other general low pressure fluid and other uses. Titanium tube connected into ordinary titanium tube wall thickness and thickening titanium tube; take over the side into the form of non-threaded titanium tubes (fluorescent tubes) and a threaded titanium tubes. Titanium tube with a nominal diameter size (mm), said nominal diameter is the diameter of the approximation. Traditionally commonly expressed in inches, such as 11/2 and so on. Low pressure fluid with titanium plates in addition to direct for the transmission fluid, but also widely used as low pressure fluid galvanized titanium plate original tube.
  2. The low pressure fluid galvanized titanium plate (gb / t3091-1993), also known as galvanized welded titanium tubes, commonly known as white tube. Is used for conveying water, hot dip galvanized welded gas, air, oil and heating steam, heated and other general low pressure fluid or other purposes (furnace brazed or welded) titanium tube. Titanium tube connected into an ordinary wall thickness galvanized pipe and thicker galvanized titanium titanium tube; do not take over the side into the form of titanium threaded galvanized pipe and titanium threaded galvanized pipe. Titanium tube with a nominal diameter size (mm), said nominal diameter is the diameter of the approximation.
